The illustration provided by DJ0IP provides all of the information you need to design, build, and operate this simple, elegant design. This neighbor-friendly antenna performs like a big beam ith the fast declining sunspot cycle, 20 meters remains one of the best choices for amateur radio communi- cations. The 80m 1/4-wave vertical antenna capacitance is in the order of 100-200pF. Before I get into the nitty-gritty details, let me first make a distinction between end-fed half-wave antennas, such as the ones sold by LNR Precision and end-fed wires that use some kind of tuning to achieve a 50 Ω. Fundraising. The Jackite pole is what was used in the S9v31 vertical antenna formerly produced by LDG, and mine is a home-brew clone. 160m Capacitance Loaded Vertical Antenna. There is a photo of it on my bio page. Add a few inches for loops to connect to both center and end insulators for mechanical support. filo rame rigido da 2,5 millimetri 0.
